Maintenance Instructions

With care, your Warpfive Stirling engine should last you a lifetime. It is supplied with all of the essential items you will need for its easy upkeep and maintenance. 

You will know when your engine needs to be cleaned and lubricated, because it will become noisy and it may struggle to get going. We recommend keeping your engine clean and free from airborne dust or ash as much as possible - the dust cover is a useful accessory which will assist in this.

It will be necessary to clean and lubricate the displacer shaft on your engine once a season or after every 1000 hours. If used extensively above 250°C (482 °F) lubrication will be required more frequently.


Follow the steps below and be sure to only use the supplied high temperature lubricant.

  1. Locate the displacer shaft - the vertical shaft that enters the top plate through the bronze bush (marked A on the diagram).
  2. Rotate the propeller until the displacer shaft is at its highest extent.
  3. Wipe the shaft clean with a cotton bud or tissue, removing any ash / dust residue. Repeat until the shaft is clean.
  4. Dip the small hex key (found in your supplied maintenance kit), or cocktail stick or pin or something similar into the vial of high temperature lubricant.
  5. Touch the shaft (marked B on the diagram) and transfer a small amount of oil to the shaft (no more than a light smear is required). Oil the entire circumference of the shaft.
  6. Do not oil the piston or any other component as this will damage your Stirling engine.

It is also advisable to tighten the bolts on the top plate once every season.  These instructions appear in your owner handbook.
